Design of Microstrip Coupledline Bandpass Filter

Microstrip Bandpass Filter simulations are included in this project paper. It has a graph, a design, a top view, and a 3D projection. The Coupled-Line Microstrip Filter is built of FR-4 material with a permittivity of 4.4 and is designed for a center frequency of 2.4 GHz. The ground is 1.55mm thick, and the air is 11mm thick. 50 ohms is the characteristic impedance. This filter is attached to the two ports and is made up of parallel-coupled lines linking the two ports. All of the dimensions have been put down. S11 values should be less than -10dB, while S12 values should be more than -2dB. The filter gives an insertion of -1.7 dB, return loss of -23 dB, and bandwidth of 1.5 GHz. Designed Microstrip Coupled Line Bandpass Filter can be used for wireless and high-frequency applications. All the design and simulations of this filter are done using Sonnet Suites Software
